shuttle eye during the run of the loom.

I-Ieretofore it has been impossible to produce an automatic threading was left hand wound which gave any dell) gree of satisfaction in operation. The shuttle equipped with a right hand wound bobbin though better also was far from perfect,'the difficulty in both cases lying in the continuous looping of the thread as it was 7 fed through the shuttle eye and alsoin the break ing of the thread during the run. Of all automatic threading shuttles used approximately have right hand wound bobbins and about 25% left hand .wound bobbins. In some mills it has proven so diflicult touse an automatic shuttle with a left hand threaded bobbin that the batteries were taken off and hand threading was resorted to in order to secure a satisfactory left hand run. y

The features of improvement of our present invention are capable of use in shuttles having either right and left-hand wound bobbins; and in either case equally fineresults are produced and ballooning and like dc.- thr-eading actionsduring the threading and run of the shuttle are practically entirely avoided. The thread is held under equal tension throughout the entire run and once in the shuttle eye escape therefrom is-impossible. I r These advantages and improvements over the prior art we secure by redesignlng the threading end of the shuttle and the utilization therein of novel thread guide and-guard members useful both during the threading both during the threading operation and suband the run of the shuttle. As these mem- 'bers may be made of wire, thecost of production of the shuttle is-considerably reduced. The construction and operationof our shuttle will be more fully disclosed in the specification which follows: v s s In the drawings we have shown as an. illustrative embodiment a shuttle threading and thread guiding and guarding equipment which not only illustrates the principles inv shuttle equipped with a bobbin in which the filling i930. serial No. 471,190.

The shuttle 1 may be of any standard construction having a bobbin chamber 2 in which is located a bobbin 3. From the forward end or throat 2 of the bobbin chamber 2 leads the threaddelivery eye 4 to which the threading slots 5 and 6 connect. I. The slot 6 conne ctsthe slot 5 with the eye 4.

In order to guide anddirect the filling operate with each otheras tosecure this re.-

sultregardlessof direction of travel of the shuttleat the moment when the threading action occurs.

We cause theshuttle body adjacent and I inforcement therefor.

left hand wound bobbin, rearwardly of the shoulder 7 and adjacent the slot 9, we dispose a member A which acts as a combined thread guide during the threading operation and guard to prevent the escape of the thread once the shuttle is threaded. The member A is a piece of wire of standard gauge bent upon itself to provide a vertical or upright portion A having a loop A the outer edge of which lies in a notch 10 in the rear wall of the shuttle so, that during the threading operation there is no possibility. of the thread entering rearwardly of the member A. The member A extends outwardly from said slot 10 as at A and then'turns and extends for wardly in a straight line as at A to a point forward of the shuttle eye 4. and inwardly of the point of oinder ofthe threading slots 5 and 6 where it again turns outwardly as at A and enters the wood of the casing where it is anchored against dislodgment. At this point the side and upper walls of the shuttle nose are cut away as at 11 to permit the thread to slide over and under the forward portion A of said guide A.

On the opposite wall of the shuttle nose approximately directly opposite the groove 10 is anchored our second thread guide and guard member B- (Fig. This member B comprises a circular anchoring portion 13 through which passes a screw 12 which passes through the shuttle wall and acts as a re- Forwardly of the screw the member B lies in a groove or channel '13 in the edge of the wall of the shuttle bodyon the side of the threading slot 5.

This portion B of the member B is curved inwardly as it progresses outwardly and lies slightly above and to one side of the portion A of the guide A'so as to leave a'narrow thread passage between the members A and B. The portion B extends forwardly beneath theoverhanging wall 11 ofthe shuttle tothe point where the threading slots 5 and 6 join. At this point it turns inwardly and follows the wall. of the shuttle along the slot 6 in a continuation 13 of the groove 13 until it is bent inwardly at right angles as at. B where it is driven into the wood of the shuttle body above the slot 6. V

I In. thecase of a right hand wound bobbin, the shuttle may be satisfactorily threaded and the thread" maintained in the eye'by a metal guide R (see Fig. 11) which is anchored at the rear end B in the shuttle wall beneath the threading slot 5 and adjacent the shoulder 7. The guideR is bent so that a portion R extends across the shuttle throat just rearwardly of the shoulder 7 where it turns for ward as a portion R and extends throughout the slot 5-beneath the overhanging wall 11 until that slot joins the slot 6 at which point it turns as at R and follows the wall of the slot 6 until it enters and is anchored as at R in the shuttle wall.

I Just beneath the bend where the portions R and It? meet there is anchored in the floor of the neck a vertical guide S which is bent outwardly and has its upper end. S disposed in the slot 10 in. the shuttle wall. This guide S with a right hand wound bobbin tends to maintain the thread in the slot 9 during the run of the shuttle and lead it thereinto during the threading operation.

Forwardly. of the bend in the member B and the j oinder of the thread passages 5 and 6, the shuttle nose is'grooved outwardly as at 11 (Figs. 2 and 3) to'permit the thread to s be drawn forward in a straight line before thesame is carried down and back through the passage 6 into the eye 4.

An eyelet member or thread guide C which is made of -Inetal wire is bent at its end C to conform to the curvature'of the eyelet 4t and is mounted in'the shuttle with the eyelet end disposed adjacent the thread outlet and its other end penetrating and passing entirely through the shuttle in front of the thread outlet and beneath the slot 6 as at C to rein force the same. As the free end of the member C is disposed in the thread eyelet inwardly of the body of the wire, it not only serves as a protection for the eyelet wall but definitely prevents the escape of the thread back into the slot 6'once it has entered the eyelet 4.

A further advantage in having the end of the member C. inwardly of the eyelet opening is that any likelihood of the thread catching on the same as it passes from the eyelet is avoided.

In the eyelet 4 we dispose a brush member B which extends across the threading passage 5 and is fastened in the opposite wall of the shuttle body. This brush serves to tension the thread during the run of the shuttle and also actsas a further guard to prevent the escape of the thread from the shuttle eye once the same is in place therein.

In the threading operation with a left hand wound bobbin, the thread is carried from the end of thebobbin forwardly into the slot 11 in the endof the shuttle which as stated above s approximately in alinement with the end of the bobbin. Under tension the thread slips over and under; the portion A of the member A and under the forward end B of the member and lies on the shoulder until it enters thethreading'slot 6. As it is drawn through this slot intothe eyelet 4 that por- I tion just entering the shuttle throat is de flected to the 'outerside of the shoulder 7 and slips over the edge thereofunder the guidance of the portion'A ofthe guide A and enters the slot 9'where it engages'the snubbing post 8 and passesinto the fibresofthe brush B, the outer end extending through the eyelet opening 4.

With a right hand wound bobbin, the thread is led forward into the slot 11' as with a left hand woundbobbin and: during such passage it slips beneath the portion R to'lie over the shoulder 7. As it 'slips from the slot 'toithe slot 6, it is deflected over the edge of the shoulder and isguided into the slot 9' by the guide S which maintains it in saidslot 9 during the run of the shuttle.

The peculiar design and arrangement of the thread guide and guards in our shuttle permits a readier and more satisfactory threading of the shuttle than anything which has heretofore been employed in this art.

Modifications in the design of the shuttle nose, the arrangementand construction of the several guide and guard members and the means and manner of anchoring the same in the shuttle nose as wellas the relation ofeach to the other may obviously be resorted to without departing from the spirit of our invention if within the limits of the appended claims.
